As a neutral and conflict resolution professional, Peggy brings years of experience as a lawyer, mediator and arbitrator to help parties to resolve business and workplace conflicts.

Work Presentation

Peggy's litigation and counseling practice focused largely on employment, non-compete and ERISA disputes. She advocated for individuals and organizations, including those involved in banking, education, transportation, telecommunications, healthcare and hospitality industries.
